My 2GR V6 4-6 weeks quoted build took 5 months and this was at least the second such build they did. Lots of next week, next week emails and phone calls. I'm a slow learner. The first one took around 5 months too. Rushed in the end to get it out by Christmas. Delivered with the race seat bolted through tinplate floor with no reinforcement plates or washers
(I'll speak to the young guy who put the seat in), incorrect (too long and not enough thread) exhaust bolts loose
(no comment); stripped thread in the chassis rail (rear cross member bolt finger tight only)
(Can't berate the guy who fitted the crossmember, he has left us), rear cross brace not fitted
(seniors moment). No surprise I suppose that I would echo Stuka's sentiments.
