I recently bought this MTB on Marketplace, paid 65€ for it. Is that a good price?

After i was taken it at home i removed Dirt guards, reflectors and gave it a quick wash and an fresh lubrication service and had reallign the Gear adjustment because it was complete off.

Equipped is an Manitou BLACK Super AIR TPC, Ritchey Aheadset, Corratec DRC DH18 26" Racing Bike Rims(What Da Fuhhxxx? WHY??), 9×3 Shimano Deore XT, Magura Julie, Front 180mm, Rear 160mm( Worn out Discs and Pads i ordered new replacement ones, original old Stock… Which specific Screws i have to order to assemble the Discs?) New Saddle and and Carbon Seat Post i will install aswell….

So was it just a good Deal or got myself won the Jackpot on this one?
