Buying advice Lexus GS 300 3. Gen

Hello community, this is my first post, and I hope to soon become an active member of the community! I am 23 years old, come from Cologne, Germany, and have had my driver’s license for five years. Although I have not had my own car yet, I have been travelling regularly with my parents’ car. I work full-time and therefore have a certain budget available. I also want to learn to screw myself on the car, and gather my first experiences with a GS 300. I drive daily to work 50km (2x25km) and once a month 600km. My budget is up to +-6k€. What repair costs should I expect? I am looking for a Lexus GS 300 of the 3rd generation. I have already looked at all available vehicles within a radius of 200km online and telephoned with dealers. My favourites: Car 1:https://www.kleinanzeigen.de/…/2985279100-216-12929 Data: 2nd hand, 240.000 km, 4.800 € (VB), BJ 2006 Advantages: – Good history – New TÜV Disadvantages : – No parking sensors & no leather seats – The seller has only had the car for a month. His reason: his wife can only buy automatic, therefore. The car did not like the woman because it is too big. I have something to consider, because I think maybe he bought a bad car and just wants to get rid of it. What do you think? Auto 2:https://www.kleinanzeigen.de/…/3001871624-216-25077 Dates: 3. Hand, 252,000km, 6000 VB€, BJ 2006 Advantages: – Seller has a complete service booklet and many inspection reports – Nice seller Disadvantages: – slightly more expensive – color not so appealing I look forward to your opinions and perhaps even to offers!
