Can I trade in my toyota camry 2011?

Its a Toyota camry 2011 Silver 4 door and it currently has 42000 miles on it. Yes, it's been runned down a lot, but I feel like the gas sucks because it runs out very quickly and I just feel like it doesn't suit me anymore. Obviously, I can talk to my deal about it, but I feel like I need a good reason for wanting to trade in my car? How can I make sure its done properly and what kind of new cars should I be looking for.in terms of a little bigger than a camry, like a sedan or Honda pruis. My car was $26000 when bought. Please any advice!

Stay with what you have.
42,000 miles is basically brand new, but if you trade it in they will hardly give you anything at all for it.
If the mileage is poor, that can be fixed.
Likely higher tire pressures are all you need, unless it has an engine or fuel problem.
Check the mileage carefully in order to be sure.
A Camry is a fairly good sized car already, so you will be disappointed with a sedan or Honda Prius, because they are smaller.

Maybe depends n who it is.

Go to a dealer. Pick out a new car. They will take your car in trade and roll the negative equity into your new car loan.
