Registration for dumies

[aluminium]

Guys

Now go easy on me, I know this is a touchy subject with there being a dedicated forum, but I can't for the life of me figure out what I will need to do and I am still hurting from having to let me car go.
I am in the process of relocating from England, I cant get my car into the country due to your fantastically strict border control volunteers.
Result, I have just had to sell the car for 2 thirds of F all. I am going to get on the wating list for an ERA 289 FIA as soon as my address is sorted out.

I have no problem buying the bits and building a complete car.

My problem lies with the registration process and any details I need to watch out for. A big thing that is worrying me is State Sales Tax that is collected at time of registration.

Say I bought the kit for $30000 the engine cost me $10000.....and that was a complete car to make it easy...... when I produce my reciepts at time of registration am I going to be paying 6.25% of $40000?

Does anyone have a break down of the process for registering the car after it is built specific for TX? you must have all done it.

Thanks Rich
