I am looking to buy an asc eurocoupe I have done quite a bit of research on them and know that they are not numbered. My question is there a tag on the inside or engine bay that would prove it is. The vin matches one that was built by asc not northtowne. Lots of weird options from what I am reading. Grey piping not red, solid roof car not t-tops,leather wrapped shift knob and steering wheel, 140 mph speedo, and no asc sticker on back has a little plaque that says asc mclaren. It also has the blacked out quarter windows as well as the plugs over back Louver vents. I am fairly certain it's not a fake but just curious what else I should look for.
