Newbee here

I visited JAL Imports today and found a vehicle that I really liked and Phil was really helpful. I have never bought a Bongo before, only normal cars from a showroom. It needs to be converted and if I want to go ahead I have to pay a deposit of 40% of the cost by bank transfer - details would be sent by text???
Before I go any further do I had a search on here for any posts about JAL but I couldn't find anything recent. I thought I read somewhere that when asking for info on a dealer I should request replies by PM. I hope that is correct?
Any help would be really appreciated and, hopefully reassuring!
