I guess my only comment would be that if you are planning on playing at the semi pro or pro level, it's probably a good idea to get a car that will not result in you having to compromise what gear you bring to the gig, or that won't be a royal pain when hauling rigs (like having to cram stuff in the back seat, etc., etc.). Of course, many only need a small cab, but if you are thinking you need a 410, then that's a different deal.
There are many small SUV's that are available new and used for about the same cost as a mid size/full size car that work wonderfully and that have 'blackout' windows that will keep your stuff safely out of site. The Honda CRV/Element, and the Toyota RAV 4 are great, and have very large cargo compartments, black out windows for security if you have to leave your cab in the car overnight, great gas mileage, and great reliability. With these or a similar vehicle, all you need to think about is what sounds good to you, and how much weight you want to deal with between the car and stage

.
That being said, I've recently been stuck with a few full sized car rentals (Camry, Accord, Impala) and the 401UL fits in the back seat of all of these with no problem. Trunk.. no way!
