For all it's worth, Rayb's correct that your SV4 is kinda overpriced... unless you have a fair bit of performance parts that you have not stated. But to be fair, the pic looks pretty cun actually...
Gearbox sounds like it's failing soon. You wanna repair that before an overhaul becomes unavoidable. I can recommend you my mech- he's really good with Hondas.
dude. no offense but... ur gearbox cant put into reverse and your price is at 45K? maybe after somemore facelifts and a good replacement of parts along with change in tyres, then maybe can pull off 45K... =) nice car though.
