You know, I see these kind of comments on this forum pretty frequently and I'd like to add my $.02.
As someone who was in the Mopar hobby for a long time and who spent over $40K on two different cars (A Hemi Road Runner and a 440 GTX) I think my point of view might have some validity.
Within the old car hobby, you frequently see this attitude directed towards "trailer queens".
I always said to those guys who opined that "trailers are for horses"...... "wait until YOU spend $3500 having pot metal trim pieces replated... and that $3500 worth of replating fits in a shoebox..... Or until you spend 3 weeks organzing hundreds of bolts, nuts, slips, and screws into indivudual baggies so they can be sent out and replated in the correct finish (black phosphate, gold zinc, etc.)-then when they come back, you have to figure out where they all go. Or you drive 3 hours one way to find a junkyard with a car similar to yours just to find a handful of hardware that is correct for your car to replace what the previous Bubba owners had replaced with home cheapo hardware I had to do this for shock absorber bolts).
Then there's the money. The last instrument cluster I had restored cost me $900. That is for a cluster with a speedo, ammeter, fuel level and coolant temp guages. No tach. No clock. No oil pressure. About as simple a cluster as you can ask for. Even though I build my own engines, parts and machining are horrendously expensive. The last paint job I had done cost me over $10K and I took the car more or less prepped (all metalwork done, body media blasted, most welding done) to the painter. it isn't cheap to do one right. You can do em a lot cheaper-but they won't be right. How about upholstery? Anyone priced high end upholstery work lately? Chrome replating?
And then there's the labor-my GTX took me 2.5 years to do. I didn't own a house ( I had a shop to work on and keep my stuff in). I didn't have a girlfriend or kids. I worked on it every night and every weekend. I spent an entire weekend waxing the bottom of the floorpans before I assembled it (it was a bare unibody).
So I can't blame a guy when he doesn't want his $40K investment rained on. Because once you restore it, as soon as you start drving it, it deteriorates. That's just the nature of cars. Go buy a brand new car and then look at it a month later, you can see the difference.
I have a buddy who has a picture of me somewhere in his stack of albums with the Road Runner on a lift cleaning the front suspension with a rag and a toothbrush after we took it to a Mopar show a couple hundred miles away. it was so much work that even though we loved driving it down, I kind of wish I had just put it in the trailer and hauled it.
So cut us car show guys some slack.
Now, if somebody is rude to you, that's a whole different story. I've always considered the Military vehicle hobby part of the collector car hobby and I've always thought that HMV's should be welcomed at car shows. In fact, there's a pic somewhere around here of my '68 383 Road Runner next to a Deuce from a cruise night almost 15 years ago here in Atlanta. I have probably been to thousands of car shows since I started going as a teenager and I have never seen anyone be rude towards the rare HMV owner that showed up.
