YES DEFINETLEY
The only reason I just bought my Impreza Spec C from Litchfields is because of their reputation as being a company I can trust/ expertise in subject / specialists / know more about the car than others/ carry out all types of mods before delivery / & offer their own warranty. (The fact that I knew bugger all about Imprezas & had to literally buy with almost eyes closed, relying soley on dealer & his reputation, apart from Subaru there was no where else I would go) Also where else could I get them to do ECu tek litchfield remap/ fit Blitz Nur Spec exhaust/ fit brand new wheels tyres, sprayed in gunmetal. fit lots of extra security/ service/ etc etc, no indy or Subaru dealership would do it.
Ok the Spec C may be more specialist as in more can go wrong than a Zed but still for a first time zed buyer it is far safer to buy from a reputable specialist or dealer than prvt sale or std indy. IMO a lot people would opt for Nissan dealerships & making ESR as wide known & public aware is not going to be easy. IMO you have to show ESR as the main 350z garage/dealership after Nissan in this country, but making the general public aware of your expertise & reputation may not be that easy. We know on these forums how good you are but we'v already bought zeds.
