amdforlife,
What you`re asking is like asking "What`s the best flavor ice cream?" First off, how long do you plan to keep this car? If you are looking to zip around for a couple of years, buy an older (94-98) sedan and add some goodies with the money you save. If you plan on keeping the car for 5 years or more, then a new 2000 might work for you.
There are just too many things to weigh when making this decision:
1) Insurance! Saving a few bucks at the dealer might end up costing in the long run. Check with your agent or Internet about what the cars you like will cost you in insurance. Spending a little more at the dealer for a different brand or model can actually save you money in the long run. Also remember with a loan, you will have to carry full coverage.
2) In for the long haul? Warranty. I don`t know Rossman but both my Hyundai`s (one present, one past) were very good to start with. 10 year, 100,000 mile powertrain warranty made them great. Plus don`t buy extended warranty, ripoff.
3) Upgrades, add-ons. If you plan to customize your car, look for aftermarket parts availability now. Dodge Neon seems to have huge aftermarket support.
4) Who the heck is selling a 2000 Maxima for 15k?
Good luck.
