I'd personally go for the 998, its the later Testastretta engine, pulls like a train and far easier to set up as they are not as highly tuned as the 748R, therefore easier to live with ......

Also being less "niche" they appear to be easier to sell on as you really need to "want" a 748R to buy one ......

Similar money £5500 - £6000 gets you a 749/999 as well at the minute, not something I'd buy but good to know you have the option ...

Best advice is buy what you "want" ... not what you are "advised" too ....
