I just bought my new car last year. U can search for my post in car section. At first I wanted to buy VW Altreon, but then i was turn off by the frameless door design. not to mention, the interior look outdated. the mileage/litre consumption is high too.
So I opted for BMW instead. reasons are it come with extended warranty & service package, reliable, classy, and quite updated.
With that budget, i recommend the following:
1. 218i Gran Coupe M Sport (the cheapest)
2. 320i sport
3. 330i M Sport
4. 330e M Sport
5. 330li M Sport

I already own X1 and X3, so i can vouch for BMW reliability (if it new).

not sure why i dont like the frameless door. personal preferences.

Fuel consumption is in the car brochure. Arteon have combine circle of 8litre/100km.
