I've been thinking about buying a 2002 coupe and wonder what I should look out for? I'm thinking 2002 because it fits my budget unless I hear a lot of negatives about them. Did the 2002 body change in 2006?
I am concern if you mean that is your total budget. You need to have a maintenance reserve budget on the side to keep this car running properly.
Check other threads to find out what costs are...you can find an independent to help lessen the labor but the consumables can still be wallet numbing.
For example: On my cars:
BMW Oil Change at Dealer: $85 (Parts and Labor)
Maser recommended Oil Change Kit only: $125 (no Labor)
BMW Cabin microfilter only: $55 (Parts & Easy DIY)
Maser Cabin microfilter only: $120 (Parts & Easy DIY)
ETC.
I have spent ~$600 in fluid and consumables for my two-year fluid replacement/replenishment service. Then add labor if you aren't DIY.
I use a (then new) 2007 BMW as a daily commuter, I could buy a used '02 Maserati 4200 for half of the E93 335i price, but the Maser's scheduled maintenance costs, tires, and gas is still not viable for me - the bimmer is still cheaper even at a $60K purchase price, running costs, and depreciation hit.
