Hi 
        I am trying to decide what is the best year of Haynes Type3 manual to buy and use as a reference for my SP2.  I guess the best way to do this is to find out which year it has the most in common with and go from there.

        Some information that I have been able to gather says that the SP2 uses a standard production Variant platform with a Z-bar compensating spring to reduce the roll rate and the stock front suspension.  The car was introduced in 72 with two models available, the SP1 and SP2. The SP1 was a stripped down version which didn't  make it past the first year.  The SP2 had only 75hp so acceleration is not quick, around 19 seconds for 0-60mph, and a top speed of 100mph (I still havent decided on whether to keep it stock, or boost these numbers. What do you think?).

        Anyway, if you could suggest a good year of Haynes or any other good books that would help, it would be appreciated.

Thanks
