matching no`s will be worth more when you sell, (for your own enjoyment while you drive , naaah)...but if you 'show' the car ,yes its worth it.... for a nice car add 5-10K for that matching no`s issue.... my car is not matching no`s,not even correct year engine...but I really enjoy the car cruising.....and 'most' people wont know ,still think the car is nice, obviously I dont 'show' my car ,it was never the intent... everyone has their own reasons for these cars ,so....if you want to show it ,yes get matching no`s, if you want an 'investment', yes... but I think all the cars , matching no`s or not are going to be having a 'value', just less so w non matching numbers car ,but at least you`re less worried about totalling it/wrecking it if its not matching no`s...I drive the heck out of mine, thats why I got my car...so I dont care about the no`s...
