Seriously non of the 90's, 00's, 10's friends, relatives I know would be interested to rent the cars you listed.

You will be better business with cars such as
- Mini Contryman, Clubman, 3 doors convertible
- Macan
- Cool looking EV like Smart #1, Volvo C40, Taycan
- Merc CLA, CLS
- BMW 4 series convertible
- 911 Carrera Cabriolet
- you know cars with more youthful image - like X4 instead of X5, X3... CLS instead of S Class.
- or show personality like Suzuki Jimny, Merc G Class
- or some well kept 70's 80's vintage boxy cars like E30 3 series, E28 5 series, Volvo 240, W126 S class for people want retro style, but not the W220 or newer S Class (not old enough).
- Myvi with popular pop culture decals

Really depends on customer target.
Unless you got source of customer not exposed to modern day pop culture, otherwise 7 series/S Class would not be preference of young generation, it is easier to rent a C Class to be honest.

The new generation is about individualism and show off personalities. The overall lifestyle image different from old generation definition of luxury.
FYI - my cousin rented a C Class with her dad's new E Class leaving at home, said too old... lol

On interior, those who will rent is all for show, they really don't care interior color.

Get a lowest spec of the vehicle, as even if no accident for sure there are scratches everywhere. People get in/out stepping on door sills, accidentally kick the glove box, kick the back seat. Get something you don't pamper.

Taking into account everyone's input and yours especially (having owned so many of the cars I'm considering), and putting myself first ahead of other productive ideas (wedding rentals etc), I am inclined to the latest, facelifted Cayenne the CKD version. Price is just right and the depreciation is manageable. Terrified at the viral contents of poor quality of the latest MB S580e sounds like bottomless pit nightmare. We have a W222 S400h at home gathering dust, hardly used these days since dad left for the better place 4 years ago.

Three exterior colours for this Cayenne:
Carrara White, Quarzite Grey and Chromite Black

Two interior colour choices:
All black leather
Two tone red and black leather

I am generally conservative where interior colours are concerned so by default would go for all black BUT this is my first Porsche - the red black combo adds a little bit of panache to the whole color scheme in the absence of the full customizable option exclusively available for CBU models. Also, the red black interior costs extra abroad but offered at the same price for our CKD version.

Black exterior with black interior?
Black exterior with red black interior?

My SA told me so far the highest demand with longest waiting list (Aug / Sep 24) is for white exterior with red black interior.

The Quarzite Grey seems a little dull to me a bit of a passe where Porsches are concerned. I actually like Crayon!

What's your take taiko?

In other news, I quite like the new BMW M340i Brooklyn Grey lol

Do you foresee the maintenance will be high? Or should be alright while within the warranty period and if I decide to extend the warranty period?

The prospect of an all black (exterior and interior) Cayenne does present an attractive stealthy proposition with the right alloys.

Before zooming town into Cayenne, I was considering the XC90 T8 Recharge Ultimate, Audi SQ8 E-tron and BMW X5 50e. I've decided I'd like something tall and well above other motorists (Cullinan will cost me kidney and I need mine, latest full sized Range is just mind boggling pricewise and maitenance I was told could even wake up the dead in their cemeteries).

1. XC90 Recharge Ultimate - timesless appearance despite its age, beautiful build quality with amazing list of gizmos but the 4 cylinder 2.0 turbo is deal breaker. It sounds too tortured one cruising along. It sounds like it's being pushed too hard. I want my engine sound to be a treat to my ears.

2. SQ8 E-tron - paid deposit had my loan approved. Last minute, I decided the rear seat was hard and I think I don't want an ECV for my long distance car. Also, I dont get an ounce of excitement when I drive it - the air suspension is too soft. I already have my Mini Electric for my daily errands in the city and love it to bits. The pocket rocket handles like its on rails, puts my MK 7.5 Golf R to shame.

3. BMW X5 50e - test drove this yesterday. But after trying the Cayenne last week, this just pales in comparison in every way. Build quality is one. When driving and at corners, I don't feel confident pushing it. Air suspension too soft - this is obviously geared to comfort.

Quality wise, once you go Porsche (I know I'm a newbie and I can't preach lol), it's hard to go back to other mass affluent Germand brands like BMW and Mercedes.

The only two SUV which I find is confidence inspiring handling wise so far is just the Cayenne and Range Rover. Others just seem to want the skin in the game.

On a separate note:
However, the BMW M340i is still calling my name I don't like it. Would you consider buying this add into your already nice collection? I'm tempted, unfortunately - most of all it being a sleeper!
