I owned a 2001 Acura TL, loved the car, but discovered after a few years it had a chronic transmission problem. At 59,000 miles the transmission died and needed replacing. However, Honda of America stood behind the car and replaced it for free. I had a loaner for two weeks since I was fifth in line at the dealership for a transmission replacement (four other cars were in the shop before mine). Apparently, through the 2003 auto year all TLs have a chronic trasmisssion problem, and Honda covered them all for 100,000 miles. However, there is no fix for that transmission so it will fail again prematurely out of warranty. After 2003 there is no problem so you should be okay if you purchase a used car after that model year. For your other question, you may want to test drive the car before purchasing since head space is a little constrained with the sunroof.
