I had my TTS in late Dec. and decided to sold it to used car dealer before our Chinese New Year (End January). That was the first TTS in Taiwan, and Porsche dealer was not happy about it, They had to buy that car back from the used car dealer since the price differences was very big, and they had only delivered 3 TTS in Taiwan....
Havn't driven 650S yet, as there aren't any test car available here. However, I had few experiences with 12C here. I must say the privilege of owning a McLaren is well above Porsche for sure. I had 996 and 991S for a long time, and loved every min. Perhaps I got used to the power and just thought I needed more so when TTS came out in Begging of Sept. I immed. placed the first order, Once I got the car in late Dec. I was very pleased with the power and how the car tackles all kinds of roads perfectly. However, the appearance of the car becomes an issue for me, since I ordered my TTS exactly the same colour as my 991S, it really didn't give me much of the "re-freshness". ITs like the power doesn't suit this car's appearance.... 99% of the people here don't even notice the differences. Especially when all the Cayenne are just parked every other block of the city... That made me feel this brand is not so special when u can paid 90K to own it (An Audi A6 3.0TDI cost US$100K here, just for ur view) This is one major factor that I had to let go of TTS, because why would I pay soo much money own a car when this brand can be seen just about everywhere....
So I thought what I needed to do is to get exactly what I want and no tolerance, and 650S comes alone, settle and yet super car appearance meets my need. Certainly the Hurcan and 458 are good choices as well, but their appearance just screaming for looks which does not suit my personality. Also the brand McLaren is not very well known at all to regular public eyes... perhaps only 5% of people aware of this brand.... (I told my Dad that I am getting a McLaren, and he thought I was getting a Macallan Whisky......) so its very low profile and yet getting the proper appearance and performance figures are just unbeatable.....
Having said all that, 991TTS is a very good car!! I got addicted to its boost power!! If you can find a used car, grap it!! the used car price will certainly make sense to own..... can't go wrong!!!
