Upgrading an old IBM ThinkPad for use in Car

[toviaheli]

I thought I'd throw this out there for some ideas.

I have an old IBM Thinkpad. It works great, just outdated. I do have XPsp2 Installed and can update to Sp3 just fine if I need to do so.

It has 2 PCMCIA Card Slots, but it is the original PCMCIA.
No USB/Pre-USB.

I can hookup an ps3/mouse to the back.
It also has a serial port and external monitor port.
Serial port (and it also has the reverse looking port -- whatever that is called).
CD-ROM/DVD player and Floppy

In order to use it as a Carputer I would need to do something to make it USB2/3 compatible.

I plan on using my TouchPro for Data, gps, etc.

Any ideas?
