They both have been reliable.I prefer the T-5 because they have better performance.The engines and turbos seem to last forever provided you change engine oil at at least the recommended intravals.The transmissions are by far the weakest link (automatics)because there was no recommended oil changes.I have found that customers that regulary flush the trans fluid say ever 40k miles do not seem to have near the failure rate than the ones that let the fluid go until it is black.Personallty I do perfer the autos because I live in an area with a lot of traffic and having driven a stick for years I got sick and tired of it in long jams.As far as electronics go the only thing that seems to give out a lot are the a.b.s. control modules and there is a link on this website where you can have them repaired much cheaper than buying them new.
