Someone on here compiled a database of all 3.0Si and M models:- https://tonyz4c.z28.web.core.windows.net/index30si.htmlI actually asked the previous owner if he had changed the seats but he said no they’re the original ones, then I noticed the extended leather on the dash, there is a slight bit of wear on the bolster but there is a local guy who repairs leather seats and I’ve seen his work on my uncle’s Jaguar so hopefully going to get that sorted
