I would not bother, problem with a replica is...... well, its a replica.
And this is a incomplete replica, ie 316 with M3 clothing . you have the looks, but not the go. And I rather buy a 323/325i for that money. if you going to spend r40k on your 316, rather sell the 316, add the R40 and buy what you don't have to build, unless you have to rebuild due to an accident.
