As the guy who started the snarky comments about the underhood gauges, I'm feeling a bit guilty; I've certainly put some odd add-ons in my cars, especially in my younger days. I can see how it would be useful to monitor AFR and fuel pressure while working on the engine. And I agree that the underhood gauges on the BaT car are a minor issue - easily removable if they bother the next owner. But somehow, they just stuck me as funny!
Actually, I thought it was funny too, particularly given the choice of gauges.
I wonder if Boonies has had a look at this baby. Maybe he inspected it and it looks great and he doesn't want to advertise this until he wins the auction.
