I wasnt bashing you for buying a used car, nor was I giving you crap for posting everyday, we all do that. Were all here to help one another. I'll agree $330 is alot better than $600 especially if it's your first car.
However, I'd think you'd get better support from the lhs if you have purchased from them. Kind of like buying a full size car from someone other than the local dealer, when the time comes for warranty work/ scheduled maintenance, you'll be treated much better if you bought it from the same place. It's a fact.
I only said this because I've been burned way too many times when I bought used equipment.
If your happy with your purchase, that's all that matters. Good luck and keep us posted.
