Opinions on buying a police Tahoe?

[richards72chevy]

I know a lot of people abuse the ls engine and they can take it.Are there any differences with the police Tahoe compared to a regular Tahoe other than the appearance?Can I put third row seat in it?I have an 02 Silverado with a lot of miles on it and I love it.Is the 03 to 06 platform just as reliable as my 02?I will probably wait until the end of the summer to purchase one because I know the price vehicles will go up in a few weeks so I have plenty of time to shop around.
