pgingl,
The approach in your selection of your car and the bottom line cost of the major components will determine if your resale will be more than your final BASE COST of build. Way too many do not research this area, then later find the final costs have bit them, so INVESTMENT no, fun car YES.
YOU CANNOT build a CUSTOM COBRA and sell it for more than your cost, your market segment of purchasers at time of sale will possibly not like your "custom" touches as to suit their tastes. You can however build a "replica" of a popular/known original car and sell it for more than you have in it.
This same analogy is found in the high performance supercar market and street rods also, so it's not amazing that it's the same when it comes to resale of a COBRA replica.
