my perfornace specialist charges £30 an hour and then what ever the parts are in cost.
i suppose it depends on where in the UK you are. you're london based jerry, and costs can often be higher.
Thats very cheap IMO. Down here the best you can expect it £50 cash in hand "mates rates" or £50+VAT for official inderpendant work.
I think the most problem with Nissan and the Zed is I beleive they ship most of the parts in from Japan. Some come from Belgium, thats where my BCM came from, but I think any engine parts will likely come from Japan.
Wonder if we could get the parts from Renault if you know their part numbers for the cars that use VQ engines (Leguna and Espace are ones I seem to remember)
my MR2 needed a new floor pan from toyota, they ordered it in from japan, took 2 attempts as the first arrived bent. so shipping in costs aren't cheap, but they should have a surplus of parts for the usual stuff.
but then all suppliers ship their parts in doesn;t make nissan special.
as for the cost of my specialist, i am lucky that i have a good place at a sensible cost, most of suffolk charge about £30 an hour ex VAT, but we're off the beaten track a bit. same reason we only pay £1.30 for a litre of normal fuel, we're 3p cheaper a litre than essex on average.
