I have a lovely SE V6, but I don't think you'd want it. I can't see someone willing to go from a 2000 Maxima to a Contour. (I'm about to get killed)
Don't get me wrong, the Contour is probably one of the best used car values around, and in terms of performance and handling the SE will thwamp a Jetta GLX, with an SVT being competitive with Audis and BMWs costing much more. That said...
Contours are quirky cars w/ problematic electronics (CEL, EGR, IMRC and other accronyms.), fragile hardware and other issue you're less likely to encounter on a Maxima, or any Japanese car. If you're looking for a car that is easy to own, stay with your Maxima.
On the other hand, if money is an issue (which percipitated ending my career as an Audi driver), then the Contour cannot be beat for value, and sheer driving pleasure, which any of us with a V6 5 spd will attest to. No domestic car has ever captured such a perfectly sized car, that performs the way ours do.
As for me, I'll keep my Contour... till I can afford your Maxima.
