Financing VW Golf incl. insurance… Discount negotiable? is the offer okay?

Hello municipality, as I have already described here, soon a financing for a Golf V is available. My question is now in how far it is possible to negotiate out a few more discounts. I have the following offer available: VW Golf V 1.9 TDI 105 PS with particle filter and including VW own insurance: deposit: 2,000 € Monthly rate: 243 € Final rate depending on final equipment ca 8.000 € Duration: 48 months Interest rate: 0.9% No compulsion to buy the car after 4 years. I find the interest rate is very okay and think the offer is not bad, right???? The insurance is already included at the monthly rate. I don’t have to register the vehicle myself. Why is this advantageous for me is described in my contribution from the insurance subforum. To what extent can I hope that I can get out a few % before ordering the vehicle and thus save a little money? Is this generally possible with financing? I thank you already in advance greeting Spone
