@Gtstorey, I agree some are not thought through.
Yes he did ask. I read that and I sent him a list (PM'd) of possible optional power trains, which would use the V2 chassis as built, but without the engine mounting points of the VW/Audi. I included the global availability of those power trains in the list and I think some other kit makers who utilize those.
This would allow folks wanting a V2 Goblin to order, but specify their choice of power train.
Lonny and team would have to build (at his extra research, expense, time, storage space, production of build manuals and videos) other multiple power train jigs and instruction to be able to give the customer what they want. This extra - modular jig option production - would get passed on to the buyer and make the V2 more expensive (possible).
If I were a niche car producer I would not do that. Lonny and team are the business folks and may see it as viable.
Many other kit producers do offer options, but if you want a Goblin then buy it. If after you buy the foundation you want to modify it, then you may do so but without the support of manuals, videos, and forum other builders.
Just my personal old age opinion. Repeat Goblin buyers wanting to upgrade and potential new Goblin owners, it is your journey, so do what you want. I'll read with interest your adventures.
Good-day!
