My 19 yr-old brother is looking to buy a used car that's about 2-4 yrs old with low miles (~25k) and around $12-16k. He looked at Audi A4 1.8T's and BMW 3's. Does anyone have any other car recommendations? He wants sporty (stick shift) and nice lookin. Are there model years to look out for on the above models? Would the audi 2.8 be better? Is a carfax report advisable? thanks for everyone's help in advance.
