Modified Cars


Asked by Apr 12, 2016 at 10:54 AM about the 2005 Mazda MAZDASPEED MX-5 Miata 2 Dr Turbo Convertible

Question type: Shopping & Pricing

I have lots of goodies added to my MazdaSpeed
Miata 2005 with a wide body kit from an rx7 but
fitted to the car. I have mods such as tuning roll bar
blow off valve exhaust racing cooling system and
custom piping. On Cargurus does Mods affect the
pricing? If so how much would someone
recommend to sell it for. I am asking 9500 with
current transmission (3rd gear isnt in good
condition but the trans is great) or 10000 for a new
one. Any price recommendations

The additional money a person spends to customize their car doesn't always mean that you will get it back... some of the things that you like, doesn't always mean that it will appeal to the masses. If 3rd gear isn't working well it means there is a problem with the syncros, or the shift forks. The transmission isn't all good. The other thing that you have to keep in mind with Cargurus is that you are comparing your car to others that dont have mods, and others that may have higher miles. Cargurus compares against year make and miles and you will find that the IMV is really close to NADA retail value for a base miata. IMV is not always indicative of the real value of a car in the market place.


I get asked this question a lot... Sorry about this comment most modified cars are worth less then a good clean original examples. Unless McLaren, Roush, Banks, or Flyin' Miatas did the work with full dyno results and prof of it! in Ann Arbor, MI these bring about $6000-7000 for a mint turbo, conv 1 owner garaged kept, 50,000 with maintenance records. It's worth what someone will pay for it.
