i love the way bmws look,they are just beautiful.
hopefully this tuesday or wednesday im going to get 2001 bmw 320i.
it looks great on its aftermarket 18' rims with low profile tires,short shifter,exhaus and interior.
im going to take to the bmw dealer on monday to get it checked,if everything will be ok im most likely going to buy it.
should i buy it?
is it worth the money?
how is its performance and reliability?
can there b something wrong with a car that bmw dealer wouldnt be able to check?
