Only my opinion ..... but the best is Intermeccanica Speedsters.
They are located in Vancouver, B.C. Canada
I personally feel that they are not "kit" cars, but more like factory built replicas.
IM Speedsters do not use the V-Dub pan. It's a brand new custom built chassis. Only avalable on IM Speedsters 1989 and newer.
They have door locks, side row up windows, windshield spray nozzles, shoulder strap seat belts etc.... a lot of fine details that I have not yet seen on Vintage Speedsters.
If you're trying to convince your wife, then go for a IM Speedster or Roadster. You can drive in the rain and have good vision on all sides with top up.
Also the defog and functions should be a factor in your decision.
Look through the Speedster owners web site and see what people have to say about their cars. But please keep in mind the year of the vehicle they are commenting on or own.
You should look at the newer models. Older Speedsters versions did not have some of the newer options.
