Questions about R 1150 R

Hello, we would like to start with the same after a long time abstinence from motorcycling again and were yesterday at the BMW dealer. As object of our desire there was among other things a R 1150 R with ABS and heating handles from 2001 with 39000 km. Condition = good, previous owner = 2, price = 6,500 Euro. Now the questions to all who know the motorcycle: 1. Can one buy the R 1150 R without hesitation ? 2. Are there major improvements in technical terms in the years 2002 to 2004 ? My husband has here any where something read of conversion to double ignition system. 3. We find the price for a 6 year old motorcycle quite high. Thank you for your answers.
