Have you tried at a classic car showroom where they tend to independently search and give you a better idea? I had an e40 that I really wanted at a point but could never get my hands on as the owner sold it for much higher than I could offer. :/ I adore all kinds of vintage cars since my childhood years. My biggest dream is to get one of these cars that you usually find exhibited in
showroom to see the best classic cars like the ones is hosting on a yearly manner and I love attending. I will take my friends this year and attend again as I've heard they will be even COVID-19 compliant, so it will be a really safe event to attend!
