However much I like the boomers on the 3200, I don't think I would want to tamper with an original model and change it's looks that much, to make it look like something else..!! I can see that any resale of a hybrid might encounter some reluctance..!! OK if it was an older car that was a bit rough but mechanically sound and the price was low to start with, then maybe a few changes would not make any difference..!!
It is a sound reasonning but it depends on markets. In China nobody cares if the maintenance book is stamped or not, they don't even know what is a maintenance book... At the Shanghai Ferrari/Maserati service center in Shanghai, supposedly the best in China, I had to specifically ask the rep if they stamped it or not and had them stamp it.
My point is that the same goes about modification, there is no car culture like we have in Europe or in the US, most of it is wealth display, they are not passionate about it and modifications like this wouldn't be a problem at all at resale. I guess it is somehow similar in some other Southeastern Asian countries, which is probably why that Australian shop sold kits in Asia, they made 8 so far from what they said. In any case, I would probably have purchased my GS as well if it had that retrofit.
Personally, I like the 3200 tail lights and think about it like some sort of piece of art that made by the designer. They were removed because of regulations, and I would justify a retrofit just because of that, I mean at least this would be my philosophy. It's like we were in 1980 and I had just purchased a C3 generation 1976 Corvette, maybe I'd retrofit the chrome bumpers because the urethane ones hat had been introduced because of the regulations were killing the design.
This said, I am perfectly fine with the 4200 tail lights, they had designers work on that as well and they surely give it their best shot! I am just adding a very light tint film on them this week-end to give them a more modern appearance
About spending 5K EUR or more on a cosmetic mod, I will probably never do that since I am usually performance oriented and it is not justified in my opinion. On top, I have my other car for modifications, I want to keep the Maser close to stock because there is not much to do with an NA engine anyway and it's already working relatively well stock. The only things I will do now that I took care of the exhaust are consumables: I'll put the best tyres I can and I'll put a set of EBC yellow when the pads are worn. Oh yes, and the spacers (I am supposed to receive my set of custom made ones on Monday) and these are what I consider cosmetics.
