I saw this kit after a friend tagged me in a comment about it on Facebook. I have to admit that this came from way out in left field, like the corner where the foul line, home run post, and fence meet on the ground. I would have thought that they would have done another GT3 car rather than a US spec GT4 racer (the Mustang isn't campained in Europe, whereas the Camaro is). Perhaps if sales are good enough, they'll do the Camaro as well(and hopefully the DTM Crossbow).
As to what UPSJuan was saying about being willing to pay a premium price for a new tool muscle car kit. You and others may be willing to drop 50-60+ bucks on a new muscle car, but the majority of car builders aren't for many reasons. Also the market wouldn't bear it. Lets say Tamiya came out with a 1970 Boss 429 Mustang, and like modern Tamiya stuff it would be beautiful. However, the price point is 55.00. Revell/Germany decides it's time to dust off it's still good but by modern standards, not great 1970 Boss 429. It's price point is 30.00. Which do you think people are going to buy. If you're thinking that can't happen, you're wrong. A number of years back, Trumpeter decided it was going to come out with a modern, recessed panel lines, new tool 1/48 C-47. Monogram decided to re-release it's ancient, but still good 1/48 C-47. The Trumpy kit retailed at 99.00, the Monogram 45.00. I saw one Trumpy C-47 in my LHS at the time, and have never seen one again. Another problem with the car model market is that it can really only sustain one manufacturer making a certain model, the exception being the Corvette, but even that has been taken over by Revell/Monogram now (AMT and Revell/Monogram both make Vettes up to C6, but AMT did not make a C7). AMT/MPC are great for nostalgia reasons, but their molds are old and tired for their more popular kits. Right now the best muscle car molds are the Revell/Monogram and will be unless Moebius decides to go there. Another problem is that there is no real entry level car kits for beginners that are priced as such. I build 1/72 aircraft and I would have no problem recommending Hobby Boss's easy build kits or Airfix's line of 1/72 WWII fighters. At 10-15 bucks, a parent can take a risk on a kid getting frustrated or bored and not finishing a kit. There is no low buck option in the car world. The snap togethers are just as expensive as the glue kits, and sometimes more frustrating. I was at my lhs years ago and Tamiya had just came out with their Ferrari 360. I was watching as this 9-10 year old boy fell in love with the car (what kid wouldn't). I knew it would be a difficult kit for a first timer and I asked the mom if it was his first kit. She said it was. I explained to her that I would have some difficulty with that kit and I had been building cars for many years and it was probably best if he started with one of the Revellogram or AMT/MPC offerings. She thanked me as I showed her where they were and left them to it. Tamiya's niche is that it is for the more experienced modeler, whereas Revell has to make a kit that is simple enough for a beginner to get through relatively unscathed and still hold the more advanced modeler's attention. Outside of it's C6, I don't think AMT/MPC has done a new tool car in at least a decade maybe longer. The good news is that you have a relatively cheap canvas to hone your skills on. Look at the engine that Mustang89 did. You can build the same skills over time. If you think detail is soft on the interior? Get your knives out and learn how to scribe. Buy aor make a set of punches for dials and window cranks. You think that the detail is soft on the chassis? There are outfits that provide small enough nuts and bolts to add that detail. You don't like the springs or shocks? You can build your own. There is enough knowledge here and elswhere on the web to get you where you want to be as a builder, not just as an assembler. This is just my opinion of where the car model hobby is at, your mileage may vary.
