I have a 1969 LM1 convertible RS that is all original numbers matching 3 speed manual, HQ stamped on engine. This car has been in my family since 1974, my dad bought it for $375 then. My question is how rare is this car, it is in mint condition and has 80,000 miles on it. Need help from some experts, I am new to the forum and no it is not for sale.
