I will also suggest the TS-50 at your price point. Ran one mobile back in the day and loved it. Like most ham radios the NB isn't much help so make sure you strap your vehicle (don't forget the exhaust). I liked the fact that I could basically control the radio with the 4 PF buttons on the stock mic. MARS is easy and also you can mod it so you can see all 8 digits. One button switched modes, one cycled power levels, one was freq up and the other was freq down.
I could "fine tune" someone on SSB, run the power up to break through a pile up, drop a couple of hundred KHz, flip over to AM, and listen to the boys on the bowl - and never touch the radio. If your vehicle is too noisy for the stock mic, you can use a powered Noise Cancelling mic, add the 4 buttons to it, and and use the +8v from the radio to eliminate the mic battery.
The radio was made up to 2002 so if you get a late model one, the caps are probably still good. Things I would recommend is changing out the lithium battery (especially if it has been sitting for a while), and definitely changing out the zero ohm resistor connected to the SO-239 with a fine stranded jumper wire.
Just my .02
