Yes pre delivery inspection is always a good idea. On both of my cars from Greg there are small things (mostly cosmetic) that I would have had him do before delivery which were difficult after I received the cars. Whether I would have been knowledgeable enough to figure out that my 2nd car (suby) had a worn out engine with leaky cylinders and blow by who knows. The creep who built the engine probably would not have given my money back anyway.
Picture this. I go for my first vigorous drive in my suby spyder. Getting on it on back roads. It blows out 3 quarts if oil through the crank case breathers. Had to walk 5 miles to and from a small convenience store to buy 5 quarts of oil. Took 3 to full and I limped it home. After complete engine rebuild with new short block I figured out the car would not cool with radiator in the back for aggressive driving. Sold the car within 12 months of getting it after waiting 2.5 years for it.
Then I built a Caterham. Life goes on.
But yes I hope this is finally that perfect reliable suby spyder that I had hoped for back in 2003. And I would like to see and drive it before it ships.
