I find it hard to believe that Peter could not give a quote on a car. If you know Peter, you know he never misses an opportunity to make a sale
In any event, that is the difference between ERA and SPF. Think of ERA more as a family owned custom build shop and SPF like one of the OEM manufacturers with a vast network dealers. Dealing with each has its plusses and minuses. As far as ERA goes, the only minus I can think of is that it does take time to get your car, but the end product is more than worth the wait. But if you are one of those people that "gotta have it NOW", than SPF is the way to go.
Enjoy your SPF, they too are nice cars!
