IT HAS A SERIAL PORT!!! Use it to tune your car!!! I have a great condition Dell Inspiron 8200 laptop. Has lots of extras and upgrades. P4 2.0ghz 1 gb memory 120 gb hard drive (new) 64 meg video with 1600x1200 resolution 4:3 screen cd burner / dvd reader wireless and wired network cards floppy drive (yeah one of those things) serial port (lots of uses for that even now) a/c power cord Lind auto-air d/c power cord docking station (just have to find it) It's running windows XP sp3. Ran Win7 on it for a while, XP seemed better. It has built in mouse pad and the pencil button mouse as well. It was my work laptop for a while. Before warranty ran out, I had the LCD screen, keyboard and CD/DVD drive replaced. It's not the newest laptop on Craigslist, but if does just as good as anything for internet and word processing. The Lind power adaptor was for a different model. It won't charge the battery, but it's enough power to keep the laptop running just fine in the car for hours on end. I used it on a drive from Minneapolis to Champaign, IL one time. I will restore to a fresh (no-bloatware) install of Windows XP before a sale. $125
