How much roughly would a quinny buzz sell for?

[SaveWaterDrinkMalibu]

It's in pretty good condition and has:

• Chassis with seat unit
• 3 & 4 wheel adaptor
• 1 newborn seat
• 2 XL seats
• carrycot, rain-cover, 2 mattresses & adapters
• seat rain-cover
• Basket & bag
• Footmuff
• tyre pump

There are 2 on my local Facebook group for £100 sold quickly

What did they have with them?

Don't know exactly they both had lots of seats

Ok thanks
Am confused what to list for as it has loads!
