I want to go to this workshop! if you know a place that can lend standard GTR exhaust, wheels with new tyres, standard suspension and can do the swap and swap back for $50 I'm totally there! there is at least 3-4 hours labour in all that, plus they need to get the parts from somewhere. most places I know charge their usual hourly rate (anything up to $100/hour) to do that work and you supply the parts, or pay them for parts they supply.
