if got extra budget, go get brv.

Alza also good car for its price, just that its long in the tooth already...2009 until now

My view on these 3....

1. Livina X-gear -
it is not new as it launched since 2011 which priced about 80k.  I personally think it is just some 'conversion' from grand livina to this somewhat SUV which is not really an SUV.  I think it should be a cross-over.  Nothing much to shout about this car though. Maintenance, i donno, try ask spare part shop.

2. BRV
Price is about 80k too. Higher sitting position compared to the other 2. It is CVT though, but you don't complain about how it is the performance and how 'cheap' is the maintenance. Boot space.. it says fold flat, but it is not in actual, the 3rd row is waste of space with such design.
A plus is rear aircond.
Okay la as it is new car and it is honda (if you want classy "I drive a honda").

3. Alza -
Compared to Livina, Interior i think Alza has more spacious, with 3rd row down it becomes 5 seater but more room at rear for loading of luggage space. The 3rd row seats can be handy if needed be.  I have it mostly folded down.
Price of course more affordable compared to the other 2 and maintenance cost definitely better than the other 2.
all 3 cars Drive-ability - pick up livina and alza will win BRV.  Go up hill too, but again these 3 is just 1.5-1.6.  Honda has higher view.  I think you yourself need to test drive all 3 cars first as no one will tell you which car suits you.

This just my comments for your reference.
*Some sharing to you and all.
a. a friend first time sit in to alza.. ooh quite spacious for this price 
b. another friend - wah.. can put so many luggages to KLIA, his car can't even fit 2 mid size (vios). 
c. IKEA - Alza can mostly slot in items with 2nd row folded.  Even BMx have to scratch head. 
d. got 3rd row... where... tada.. 
Alza not the best car, but definitely a good car.

underpowered...it depends.. I have no issue with it.
